SOLDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,762, dated November4, 1890.

Application filed June 5, 1890. Serial No. 354,363. (No model.)

To all whom it may concern:

Be it known that I, VVALTEB J. PHELPS, a citizen of the United States,residing at Salem, in the county of Columbiana and State of Ohio, haveinvented a new and useful Machine for Soldering Cylindrical Tin Cans, ofwhich the following is a specification.

This invention relates to machines for soldering cylindrical tin cans;and it has for its object to provide a device of this class which shallbe simple, durable, and efficient, and which shall be so arranged as topermit two workmen to use the machine at the same time, one of saidworkmen being provided with tools for soldering the side seams while theother secures the bottoms upon the cans.

With these ends in view the invention 0011- sists in details ofconstruction to be hereinafter more fully described, and particularlypointed out in the claims.

In the drawings, Figure 1 is a perspective view of a can-solderingmachine embodying my improvements. Fig. 2 is a longitudinal verticalsectionalview of the same. Fig. 3 is a vertical transverse sectionalview. Fig. 4 is a rear View. Fig. 5 is a detail view of the slottedsupporting-plate.

Like numerals of reference indicate like parts in all the figures.

1 designates the base, which consists of a metallic plate having anopening 2 formed therein. Mounted upon .the said base is a rectangularcasing, which is composed of an outer and an inner shell, which aredesignated, respectively, 3 and 4. Between the said shells is a space 5,which may be left open, or which, if desired, may be packed withasbestus or with any suitable non-conducting material. The bottom of theinner casing 4 is provided with an opening 6, in front of which it has atransverse slot7. The bottom .of said casing is also provided with aseries of longitudinal ribs or flanges 8, the function of which will bepresently described. The

rear end of the shell 4 is open and is made flared, as shown, the saidflaring ends being engaged by a flange 9, which depends from the rearedge of the outer shell 3. The latter is provided with lugs to receivescrews or bolts, by means of which it is secured to the base, thusserving to retain the inner shell inits proper position upon the latter.

The top or upper side of the outer shell 3 is provided with themelting-pot 11, and the upper surface of the top of the said shell,which is designated by 12, is made to slant from its outer edge down tothe edge of the said pot. This is for the purpose of preventing themolten metal contained in the latter from overflowing, it beingnecessary in practice to keep the said pot about level-full of thesolder. At or near the upper edge of the said pot is formed a shoulder13, which serves to support a plate 14, having a slot formed therein.Upon the upper side of said plate adjacent to the rear edge of the slotis formed a lip 16, which may or may not be tinned over. The upper sideof the plate 14 is covered with a coating 17 of asbestus, which servesto prevent the upper surface from being tinned over when the solderwould be liable to flush up over the surface of the can when the latteris being operated upon.

The shell or casing 3 is provided with laterally-extending lugs 18,supporting, respect ively, a guide 19 and awiper 20. The former consistsof alongitudiually-slotted plate provided at its inner end with abeveled head or enlargement 21. construction shown and described inLetters Patent of the United States issued to me on the 17th day ofDecember, 1889, No. 417,682, is provided with a piece of asbestus cloth22, held detachably between the clamping-jaws 23. The guide 19 and thewiper 20 are both mounted adj ustably and detachably upon the lugs 18 bymeans of bolts or set-screws or in any other suitable and convenientmanner. The said devices also serve to press upon the ends of the plate14, thus retaining the latter in any position to which it may have beenplaced.

The melting-pot is provided with an abutment 24, upon which is mountedan upright 25, to the upper end of which a frame 26 is pivotallyattached by means of a bolt or in any other convenient manner. The saidframe serves in practice to support the can which is being operatedupon, and being made of open-work, as shown, it permits superfluousrosin to drop through, instead of accumulating upon the said plate,where it would to some extent interfere with the operation of thedevice.

The wiper, which is of a 28 designates a damper or deflector, whichextends through the slot 7 in the bottom of the inner shell 4 in anupward and forward direction. In practice the burner, which supplies thenecessary heat, extends through the opening 6, which is directly belowthe melting-pot. The said deflector may, when desired, be pushed upbetween the burner and the bottom of the melting-pot, thus preventingthe solder from burningin the event that for a period it shall not bedesired to utilize the said melting-pot.

The damper or deflector 27 is provided with ahandle 28, by means ofwhich it may be conveniently manipulated. Suitable means may also beprovided for retaining the said deflector inany position to which it maybe adjusted.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of my invention will bereadily understood by those skilled in the artto which it appertains.The tools which are used for solderingthe side seams are placed upon thebottom of the inner-shell'3, resting upon the ridges or flanges8,-wh-ich form a grate to support the said tools. The workman stationedat one side of the machine solders the side seams and passes the cans tothe next workman, who places the bottoms in position, and, placing thecan upon the-supporting-frame 26 with its lower edge resting in the slot15in plate 14, rotates the can, thus causing the bottom seam to besoldered. V

In this class of devices the casing of the machine, or stove, as it iscommonly called, is usually made of only a single thickness of metal.Owing to this, it soon becomes very hot, rendering it exceedinglyuncomfortable for the operator, who is obliged to occupy a position. inclose proximity to the said stove, By my improvement the space betweenthe innerand outer shells, which may either bea dead-air space orpacked, as herein described, with non-conducting material, keeps theouter shell comparatively cool.

Can-soldering machines have heretofore been constructed in which aslotted supporting-plate has been used to guide and support the canduring the operation. The objection, however, has existed that thisstrip or plate will soon become tinned over on its entire upper surface,thereby causing the solder to flush up over the sides of the can, thusincurring a waste of material and making less perfect work. By myimprovements these defects are thoroughly avoided. The combination withthe device of the Wiper herein described also serves to make moreperfect work and to avoid unnecessary waste of ma terial.

If for any reason it shall be desired to temporarily suspend the use ofthe melting-pot,

the deflector may be moved into position under the latter, and thesolder contained therein thus be prevented from burning.

While I have in the foregoing described what I consider to be a simpleand efficient construction of my invention, I desire it to be understoodthat I reserve the right to any changes and modifications in theconstruction of the same which may be resorted to without departing fromthe spirit of my invention.

Having thus described my invention, I claim 1. In a can-solderingmachine, the combination of the inner shell or casing, the bottom ofwhich is provided with an opening for the passage of the burner, theouter shell or casing having the melting-pot in its upper side, aslotted supporting plate arranged transversely across the melting-potand having a covering of asbestus, and an upright arranged adjacent tothe melting-pot and having a hinged supporting-frame, substantially asset forth.
